Problem description: I have an Acer ED7-34 widescreen monitor and a MacBook Pro 15" Mid-2012 Non-Retina. When connecting my laptop to the monitor using a Mini DisplayPort to DisplayPort cable, my monitor only supports 1080p. It will not show me the 1440p resolutions (or others) that it should support. For 1440p options, it only shows me a 3440 x 1440 which my computer does not support. The Display window gives me an option for a 3440 x 1440p, which by Tech Specs the laptop does not support. When I select it, the monitor goes black and the monitor shows no signal. When I have 2560 x 1080 selected, the text is fuzzy and it seems a bit stretched. Same with 1080p selected. According to my tech specs, my laptop supports an external display of up to 2560 x 1600. So, I should see more options.

It seems fairly straight-forward so I'm not sure how I would fix it. The one thing I do have is a new Mini DisplayPort to DisplayPort cable coming in, but the fact that the cable will let me do 1080p but not anything else suggests to me that it's not the cable. I also hooked up my work laptop, a Dell Latitude, via USB-C to HDMI and the monitor worked perfectly.

You are never going to be able to use tht DP port to run that monitor at native resolution. 2560x1440 is much lower resolution than 3440x1440. if this were Windows I'd tell you to open up the NVIDIA control panel and force GPU scaling, then choose Aspect Ratio, then select resolution 2560x1440. That would get you full-resolution of the screen at 16:9 But because this is MacOS and Apple are loving video control freaks, you're stuck with whatever scaling and resolution options are provided. Can you try Boot Camp? You can download a trial version of Windows 10 that never expires. defaultluser fucked around with this message at 08:25 on Mar 1, 2019 |

Unfortunately, you only have the bandwidth for the 16:9 unscaled (2560x1440). If you want ultra widescreen, you're forced to use a lower resolution (2560x1080). 2560x1440 = 3,686,400 pixels, 16:9. This is the limit your device can handle. 3440x1440 = 4,953,600 pixels. 21:9.Way beyond what your video card can handle. 2560x1080 = 2,764,800 pixels. 21:9 This is well within limit your device can handle, and is the only other standard ultra-widescreen resolution. Unfortunately. it has to be upscaled, which means blur. The wider the screen, the more pixels your video card need to push...even if the vertical resolution is unchanged. defaultluser fucked around with this message at 15:22 on Mar 4, 2019 |
